产品描述:基本信息 产品编号: L10607  产品名称: Lexacalcitol CAS: 131875-08-6   储存条件 粉末 -20℃ 四年     分子式: C29H48O4 溶于液体     分子量 460.70     化学名:  (1R,3S,5Z)-5-[(2E)-2-[(1S,3aS,7aS)-1-[(1R)-1-(4-ethyl-4-hydroxyhexoxy)ethyl]-7a-methyl-2,3,3a,5,6,7-hexahydro-1H-inden-4-ylidene]ethylidene]-4-methylidenecyclohexane-1,3-diol Solubility (25°C):   体外:   DMSO   Water   Ethanol   体内(现配现用):   <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;⼀旦配成溶液,请分装保存,避免反复冻融造成的产品失效。   生物活性 产品描述 一种维生素 D 类似物,是细胞生长和免疫反应的有效调节剂。Lexacalcitol 可用于移植排斥反应、银屑病、癌症和自身免疫性疾病的研究。 靶点 VD/VDR 体外研究 Lexacalcitol inhibits cell proliferation by 50% at 10-12 M (14,000 times more active than la,25(OH)2D3) in human histiocytic lymphoma cell line U 937. Lexacalcitol inhibits interleukin-1-induced mouse thymocyte proliferation by 50% at 3×10-16 M , allogeneic stimulation of mouse spleen lymphocytes at 5×10-15 M. 体内研究 Lexacalcitol (0.5 mg/kg/2 days; i.p.) in combination with cyclosporin A (CyA) can prevent autoimmune destruction of syngeneic islet grafts in spontaneously diabetic NOD recipients. Animal Model: Male and female spontaneously diabetic NOD mice Dosage: 0.5 mg/kg/2 days Administration: Intraperitoneal injection Result: Single treatment with KH1060 or CyA did not result in statistically significant suppression of early graft failure, while the combination of KH1060 and CyA can prevent early graft failure and delay graft rejection of xenogeneic islets in spontaneously diabetic NOD mice.
